reaction rate: Facts & Related Content
Did You Know?
- The reaction rate is generally highest at the beginning of a reaction, when the concentration of the substances reacting is highest.
- Reaction rate increases when temperature increases, when concentration increases, and when solid reactants have more surface area available (e.g., when the reactants are in smaller pieces).
- Catalysts are chemicals that raise reaction rates without being consumed in the reaction.
